Abstract

A light source device is obtained, which has an enhanced light distribution characteristic with sufficiently homogeneous diffused light and can be readily manufactured with a simple configuration. The light source device has a substrate, a board-like first reflectorerected vertically to traverse a center section on the substratewhile both side surfaces face outward, and a plurality of LED chipspositioned on the substrateas a plurality of light emitting elements so as to surround the first reflector. At least both side surfaces of the first reflectorhave a light reflecting function. Thereby, a light source device is obtained, which has an enhanced light distribution characteristic with sufficiently homogeneous diffused light and can be readily manufactured with a simple configuration.
